Thanks for writing your query.
My advice would be take rest, Ice fomentation, keep limb elevated and put a compression bandage (crepe bandage) along with ibuprofen
and trysin to reduce pain and swelling.
If the swelling and pain persists you may require an x ray
to rule out the fracture
especially hair line fracture.
Take care and I shall be glad to answer any further query.
